To all wir/om it may con/cern: la Be it known that ANDREW T. MACCQY,

of Dover, in the county of Norfolk and State of Massachusetts, haveinvented certain new and useful 'Improvements in Type-Writing Machines,of which the follow-ing is a `specification.

This invention has relation to type-writing machines, and moreparticularly to those machines which are electricallyv operated, such as"page-printing stock-tickers, so called, althou h many -features oftheinvention are 'ca a l'e of embodiment in typewriting mac `nes of othertypes.

The embodiment of the invention illustrated onthe drawings consists ofvatypewheel which is rotated/and selectively positioned by aAhey-controlled electric motor. The type-wheel and the motor are mountedto oscillate about a vertical axis to feed the type-wheel across theconcavev face of a platen, and an electromagnetic mechanism is employedfor impartingthe feeding movement thereto. A' spring is employed forreturning them but it is not rendered active, except when they reach apredetermined vpoint in their feed and whenone of the shifteys ismanipulated. The same electromagnet is used for imparting an impressionstroke to the type-wheel radially of the axis of oscillation of themotor. and 4the typewheel as is employed for the feeding opera.- tion.Automatic paper-feeding mechanism is employed, 'and it is actuated bythe said electromagnet when the feeding mechanism has fed the type-wheelto the end of a line. The electric motor and the said electric magnetderive their current from the same source which supplies, first, analternating current, which energizes the motor to rotate the type-wheel,but does not affect the electromagnet, and then a direct current to holdthe Atype-wheel against further rotation and to energize the magnet andcause it to perform its functions..

0n the type-wheel there is a line of c aracters and blank spaces, thealternate characters and spaces having a potential printing relation tothe laten. By mechanism controlled by a shi t-key the type-wheel isrotatively shifted one space to either of two positions relatively tothe motor-shaft to which it is geared to bringthe former nonotentialcharacters and spaces into )otenpurpose.

` tial printing relation to the platen and to remove the first-mentionedcharacters and spaces to a non-potentialI relation, so that eachcharacter-key on the keyboard may he used for causing the printing ofeither of two characters by the type-wheel. An electromagnetic mechanismconnected in multiple with the electromagnet hereinbefo're referred tois automatically cut into circuit when one -of the shift-keys ismanipulated to pre ent the feeding of the type-wheel on the shifting ofthe `type-wheell forr otherwise the feeding -.would occur, since theshifting is efectedv when the type-wheel has been positioned and has hadthe impression-stroke imparted to it by the said electromagnet.

Either of the shift-keys operates to render the carriage-returning meansactive by partially closing a branch circuit to an electromagnet, whichlifts a feeding and a retaining pawl 'from a ratchet on the type-'wheelcarriage, the complete closing of said branch circuit being effected bya switch, which is automatically operated when the type-wheel hasreached the end of a line.

On the accompanying drawings, Figure i represents in side elevation amachine embodying the invention. In this figure the platen for the paperand the paper are illustrated in vertical section. Fig. 2 represents aplan View of the same. Fig. 3 represents a front elevation. Fig. 4represents a rear elevation, partially in section, on the line 4 4- ofFig. l.

.I desire to have it understood at the outset that Athe machine shown inthe drawings thus .briefly describedis one embodiment ofthe many ofwhich the invention is capable, that the invention is not limited to thedetails of construction of the machine or to any 'part'icular formoftransmitting or controlling devices, and that the phraseolo ouslyrotated with a step-by-stcp movementv by a novel motor which I havedevised, the Vmotor being energized by an alternating current/,in whichthe changes of polarity are too re uent to cause the mechanicaloperation ft 'e various mechanisms by electromagnets are sufficientlyinfrequent to effect one'ste in the rotation of the type-wheel for eacThe current is supplied to the motor through a transmitter orpole-changer, which is automatically sto ped upon the depression of akey to cause t e transmission of a direct current to the motor,whereupon the motor and the type-wheel are stopped in their rotationwith a ty e or space presented to the paper correspon ing to said key,and the' electromagnetic mechanisms are operated to f eed or return thecarriage, impel the typewheel 'toward the paper, or feed the-paper, asthe case vmay be. The type-wheel is so geared to the motor and the motoris so constructed that the rotation of the type-wheel is'substantiallsynchronous with the rotation of the 4po e-change'r or transmitter andof'th moving contact of the sunflower. The

which l employ in the specificaticnand c aims is for the. pu'iplose ofdescription nd not of limitation.

keys on the keyboard are respectively elec- "trically connected with thestationary con-- at a main or central station where the transmitter isplaced; 'lhe key b is the spacingke and the keys b b2 are what aretermed s ift-keys. lhe remainder of the keys are character-keys. In thesendingmechanism I propose to reduce the number of the character-keys,so vthat one key may be used for each of two' difierentcharacters--as,for instance, one key may be used for the letter a and numeral 1,another for b and 2, and a third for c and 3, cc.V Each of these keys bb b2 b3, &c., is connected by a4 separate branch circuit Ac c with thestationary contacts d of the sunflower D. The rota arm d of thesunflower is on a yielding y-driven shaft E, said shaft having thereon astop-wheel .F and the pole-changer or transmitter G. e indicates acircuitJ having a source of electrical energy included therein, saidcircuit including the arm d and serving as the return-Wire for thebranch circuits c c. In the circuit e is placed an electromagnet e2, thearmature 'e3 0f which is mounted upon a movable stop member e4, arrangedin operative relation to lthe stop-wheel f and normally held awaytherefrom by a s ring e5.

' The stop-wheel F is provided with a p urality of teethf equal innumber to the keys of the keyboard, which, as previously stated, arealsol equal-in number to the contacts-'fl on the sunflower. Thepole-changer or transmitter G has up'on its periphery a d'plurality ofcontacts g', arranged in lstaggere relation with their ends overlappingor pro'ecting past each other. The shaft Eis 'eldingly driven by anysuitable means. ot illustrated.) Bearing upon the periphe ofthepole-changer are two brushes g2 g3, vif'liich are connected in twodifferent circuits g4 g5 ofopposite polarity. The two circuits g4. g5'have separate sources'of electrical energy, (indicated at g 98.)' Thebrushesg2 gf areengaged alternately by thecntacts g iq; as the polechanger rotates, Arranged etween said brushes is a third brush g?, whichis siicce'ssively engaged by all of the contacts g', this brush g7 beingconnected with the main working circuit, which is indicatedat H,'theconductor of which is connected to a binding-post 1111 on the baseof themachine, but

lOO

insulated therefrom. The machine has another binding-post 112, fromwhich the circuit H is grounded, there being a ground connection betweenthe sources of electrical 5 energy g'gs, as illustrated 'in Fig. 18. Thetype-Wheel, Which is indicated as a Whole at 27, has u on its'peripherysubdivisions Which are doub e in number lto the keys on the keyr board.f these divisions six are blank, as io shown in Fig. 18, the remainderbearing the usual types which are used in type-Writers orprinting-telegraph machines. The six blank s aces are indicatefhpt i ifi2 t3 t4 i5. When t e spacin -key .b is 1depressed, a cirr cuit isclosed to t e corresponding contact en the sunflower, and When therotating arm d thereof reaches that contact theelectromagnet e2 isenergized to cause the stop e4 to engage the corresponding tooth of thestop.

I have described suitable devices for con- 3o trolling the operationofthe machine; but it y "will be understood that others may be sub-AEtitlIted, if desired. I-shall nowproeeed to describe the machine.l

Framework--ln ,f generaly the machine is g5 provided with a Wooden base19 and a metailie base-plate 20, from Which arise the brackets forsupporting the various operative dparts or mechanisms of the machlne andwhich will be referred to in connection with so the parts which theysupport.

21 indicates the main bracket or standard, which extends'upward from thebase-plate and in which the carriage and the motor which drives thetype-Wheel are journaled i5 u on a vertical axis. This bracket islateral y extended near its base to furnish supports and bearings forsome of the parts of the machine.

51o constitutes a part of theearriage or. which the type-wheelisrotatively mounted and pivoted, so that it can be impelled to thepapen'the paper being arranged vertically and supported by a platen, aswill be de- 5 5 scribed.

Referring to Fig. 6, it will be cbr' 'l that the bracket` 21 is providedwith two oppositely-projecting studs or pins-22 23, which are arrangedin vertical alinement and which `6c operate to rotatively support thecarriage,

the type-Wheel, and its motor.

The motor, which will be described subsequently in detail, is indicated,as a whole, at 24 in Fig. 1 and is provided with sockets for 6 5I thereception of the pins or studs 22 23. To

the rear end of the motor is attached a forked bracket 25, (see Figs. 1and 4,) in the lower end of the arms of which is passed a pin 26 forsupporting the type-Wheel and its carrier. The motor and the bracket 25constitute a carriage for the type-Wheel and its carrier,

by-step movement about the studs 22 23 from left to right to permit theprinting of a line of characters across the sheet of paV er and to bereturnedfrom right to left with a single continuous movement', themechanism by which it is accomplished being hereinafterl described indetai The type-wheel 27 is loosely placed upon an upright shaft 28, theup er end of which is journaled in a yoke 29 an 'its lower end in astepO, pivoted on and supported by the pin 26. The bifurcated armsconstituting the yoke 29 are piv- `oted at their lower ends on the saidpin 26, so that the ltype-Wheel may be moved bodily about the axis ofthe pin 26 in addition to its movement about the vertical axis of themotute the carrier for the type-wheel, and they .are held away from thepaper or sheet to be printed by a spring 31, attached to the yoke and tothe bracket 21. 0n the shaft 28 is placed a bevel-gear 32, whichintermeshes with and is driven by a bevel-gear 33 on the shaft 34 of themotor 24. The rotation of this shaft 34 effects the rotation of theshaft 28 and of the type-Wheel 27.

The metan-The motor itself is illustrated in detail in Figs. 12 to 16.lt comprises a plurality of permanent magnets 35, arranged radiallyequidistant about the shaft 34. Each of these magnets is in the form ofa bar or strip which is arranged longitudinally with relation to theshaft 34. They are alternately disposed as regards their poles, so thatat each end of the motor the north pole or positive end of one magnet isbetween the 4south or negative poles of the two adjacent magnets. Withinthe permanent magnets is arranged a coil 36, wound upon a bobbin 37 andcovered with a layer of insulation 38. This coil is connected in serieswith the polechanger or transmitter, so that an alternating current issupplied thereto, there being about four thousand altermitions orchanges of polarity per minute. Secured to the shaft 34 is an armature,(in dicated as a Whole at 39.) This armature consists of a cylinderhaving its ends expanded so as to rotate in close proximity to the polesof the pern'ianent magnets 3. .Ea-eh of the expanded ends 40 of lingers41. ln the form shown there are four permanent magnetic poles at eachend of the motor, and there are six lingers on each. end of thearn'iature. The armature itself is formed of soft iron, so that itmay bemagnetized by the coil 36, and it is supported i upon the shaft 84 bybushings 42.

and they are adapted to be fed With a steptor. Tle shaft 28 and the yoke29 consti- IOO is slotted or out away to provide a plurality f 5 Themotor-shaftis at one .end journaled yen a easin or .cap 18() at the .endof the motor .and in racket. 181 at the other end. .(See .-Fig. l.)

5 Uponlthemotor-,shaft 34 is 4secured a vratchet-wheel 43, with .which alazypawl 44 .is in engagement for the purpose of preventing areverserotation ofthe armature. A

The operationof the motor is` as follows: xo The passage ,of a current.of positive polarity through the coil 36 magnetizesthe armature .39,sothat one .end thereofzbecomes of posi- .tive magnetic polarity and theother of negativepolarity. At the positive .end ofthe ariq maturethengers 41 are attractedby .the negative lpoles of the permanentmagnets and are repelledv by the positive poles of said magnets.Inasmuch as :there are sixl fingers and -four.po1es, .the ngers will bedrawn by the 2o magnetic polesof opposite polarity sufficientlytoeffect. a partial rotation of the armature. Upon a change of polarit inthe current through the coil 36 .the arity of the armature 39 will beimmediate y changed,

`-.so lthat the ingers which were previously positive will becomenegative and will be attracted b the Qsitive ermanent magnetic `.polesanvwill c repe ed by the negative poles. 'Thepermanent magnets beingaltero .na'tely oppositely arrangedwith relation to theirqpolarit theattractive force' upon the larmature will be equal at both endsthereof,and for each change of polarity in the operating-currentthrough the coil36 the armature 39 andthe shaft 34 will. be advanced one step.

` Ihave stated .that .there are tour perma.

. nent magnetic poles at each .end ofthe motor and six n .It -willbeunderstood, however, that I may .14o employ. any suitablenumberoflingers and .permanent magnetic poles. In order to assistinthe advance.movement .or step bystep rotation -of the armature, it will .be seen'4that the ends :ofthe permanent magnets are beveled, so that the endsurfaces are-successively to one side of radii passing from the axisofthe shaft 34 through the central longitudinalplanes of the .permanentmagnets. Byreason ofthe number of fingers and per- -.5o manent magnetstwelve alternations-of the .current .or changes of' polarity thereofwill effect` a complete rotation of the motor, and

hence the motor must be geared to the typewheel accordingly. Ithappensin the pres- 5 5. ent case thatthere are twenty contacts on thepole-changer, and hence the motor is'gearedI 'A It will `be seen thatsecured to the mot or. is

This pawlv is held in engagement with the ratchet by a.helicalspring 56,.as,b.est;showf1 in Fig. 1.

TypefwheeZLcctuctmg mecamsm-1 have now explained the mechanism forfeeding the typefwheel' carriage forward step by step .against thepaper.

and the mechanism for returning the carriage to its initial or startingposition, and i shall new explain the mechanism for striking thetype-wheel against the paper for effecting the printing of a characterupon the paper, and this includes the following devices: Pivoted uponthe pin 26, which, as has been stated,-

is supported in the forked bracket 25, is an arm 70, which is connectedby a brace 71 with the yoke29, so that when the arm 70 is raised thetype-wheel carrier is oscillated about its axis and the type-wheel isthrown forward to engage the paper, whichis held in pro er relationthereto, as i shall hereinafter exp ain. The armature 52, which,as'previously stated, is'secured to the shaft 53, is on an arm 72, whichprojects under the end of the arm 70, as shown in Figsjl and 17, so

that each timethe armature 52 is attracted by the electromagnetic coils51 the typee wheel carrier is oscillated about its axis to effect theimpingement ofi the type-wheel nasm ch as the attraction of thearniature52 y the magnet simply withdrawszthe feeding-pawl into the i positionwhere it ma be carried forward by or ngers (indicated at 81 81 82.1

, The platen- The aper A is-shown as be? ing drawn upwardly 'rom asuitabie roll, (not shown,) arranged below the machine, and it is heldand supported against a concavo-conveX platen, as indicated at 80. inplan view this yplaten forms the arc of a circle of which the axis ofthe type-wheel carriage is the center. It consists of an uprightmetallic shell against which the paper is held by a lurality heseiingers are resilient, the fingers 81 being supported by a strip 83,attached at its ends to the side edges of the platen, which edges arebent inwardly tc form guides lfor the 'side edges of the paper strip.The finger 82 is supported by a bracket 84, which serves anot ierfunction to be described.

Zaper-jieeding Imechanism. The paperI is fed upward with a step-by-stepr vement by two coacting disks, wheels, or rolls 85 86, of which thelatter is positively driven. The

roll 85 may be shod with hard rubber', itnd it is loosely journaled in aforked. arm 87, jour-A naled in a bracket 88. To the shaft 89, to whichthe fork 87 is secured, is formed or attached an'arm 90, by which theroll 85 may A spring be moved away from the paver. 91 exertsmits tensionupon t e shaft 89 to hold the roll 85 yieldingly against its coactingroll 86 or the paper, which is interposed between them. It will beobserved by an inspection of Fig. 1 that the platen is apertured toreceive the roll 85. -The roll 86 is preferably corrugated or toothed topositively engage the paper and feed it upward by the laten and thetype-wheel. This roll is oosely journaled on a stud-shaft 93, which is journaled in standards 921 95, rising from the base 20. Movable with theroll cr wheel 86 is a ratchet-wheel 96, these two wheels being Securedtogether by a hub 97, on which they are rigidly mounted. These wheelsmay be secured :friction tight on the hub, as shown, or they may beotherwise secured as convenlence suggests.

On the shaft 93 is a paWl-carrier 98 with a pawl 99 in position toengage the teeth of the ratchet 96. The paw -carrier is secured upon theend of asleeve or hub 100, to the other end of which is secured an arm101, which extends substantially horizontally forward and which carriesupon its end a stud 102. A spring 103 encircles the shaft 93, one end being attached to the standard or upright 95 yand the other to the arm 101to move the pawl reversely around the ratchet when permitted. Theratchet is held against reverse rotation by a spring-retaininfr paw1104,as shown in Figs. 1, 5, and 6. The stud or projection 102 is normally enaged by a' projection 105 on a pivoted latc i 106, the end of whichextends upwardly into the path of a tripping-stop 107 on theratchet-segment 50,

so t at when the carriage has been fed across the aper the stop willengage the end of the latcfi 106 and move it to the position shown inFig. 5, so as to release the stud 102 and permit the spring 103 to swingthe pawl-carl 4rier to the position shown in Fig. 6, preparatory tofeeding the paper upward one step. This actionv of the spring, however,does not take place immediately upon the release of the stud, but isdependent upon the operation of the carriage-feedin Ina net.

Rigidly secured upon t e s aft 53 is an arm or lever 108, which projectstoward the platen and lies above the stud 102, extendin pastthe latch106. When the type-Whse carriage has'nearly reached the limit of itsmovement across the paper, an electrical impulse, sent through theelectroma'net 51 by the manipulation of a space or other key by means tobe described, causes the attraction of the armature 52 and the liftingof the arm inasmuch as at this time the B 'seancev tnppedt, the spring'103 will reversely actualte the1w awl=carier 98 and move it' to the po*-s'tion s own in Fig. 6. As soon as the curgeht fails in the l'eeti'ornaet 51 the spring 57 previously referred to, will return the rockm` they'pe-wheel carriage has-accom lished a ortion of its return. movement. tmay be stated that the arm 108 oscillates once'foreach feeding stepimparted to the type-wheel carriage; but thls can have no effect uponthe r 5 paper-feeding mechanism, exce t when the latch 106 has been triped by t e stud 107.

.` To move the latch to an hold it in its lockin position, the lower endof the latch is secure upon a shaft 109", about which is coiled' a z'ospring 110, the ends of which are attached,

res ectively, to the shaft and to the base 20, as est illustrated inFig. 4.

As thus far described it will be seen that when the carriage has reachedthe limit of its z 5 movement across the paper the carriage will beautomatically returned upon the depression of a key in the sendingapparatus and the paper will be advanced one step.

Mechanism 1s rovided by means of which' 3o the aper may e fed Aone ormore steps prior to t e return of the carriage to its initial'orstarting point; but 'inasmuch as this depends upon another feature ofthe machine I 'willrst explain the operation of'the type1 3 5 shiftingmechanism.

Typle-sh'iftlng mechanism-J have stated that t ere are double thenumber of divisions on the type-wheel that there are keys, so that A itis-'necessary to at timesshift the type? 4o wheel on its shaft in orderto bring the proper 'character in printin relation to the paper, andthis is accomplis ed by manipulation of the keys b b2 of the keyboard Band mechanism controlled thereby, which Ishall del scribe.

Thetype-wheel 27 is loose on the shaft and i's provided witha hub 120,(see Fig. 7,) having oppositely-extending arms 121 and 122, to which arepivoted fingers 123 124, lrespec- 5o tively. The hub 120 has stillanother arm 125, which is at right angles to those pre- 'viouslydescribed and which has a down-l wardly-pr'ojecting in 126, the end ofwhich i's' beveled.

two stops 129 and 130, between which the pin l 126' may. play.

The hub 127 is also provide with another arm134, havin uides 135 for the two fingers 123 124. Afgf ed to the frontof the carriage is the bracket .84, to which reference has beenpreviousl made.

Hence upon the pressing of ashiftrey on the keyboard the type-wheel'shaft 28 will be stopped with ablank'space opposite the paper, and as the type-wheel is moved towardthe pap'e'r the end of one of the fingers 123 or 124, as the case maybe, will engagethe insulated block 136, so that the' type-Wheel will bevshifted "one space in ofie direction or-the otherirelatively to itsshaft.

In Fig. 8 the type-Wheel has beenstopped withthe finger 124 opposite the block 136,' and in Fig. 9 the position ofthe parts is illustrated -after the type-Wheel has been movedA forwardtoward the paper to cause the end of the finger 124 to engage the blockand shift the type-wheel relatively to its shaft.

ceases ring particularly to- Fig. 6, it Will be seen that the carriage-feeding paWl is provided with a tailpiece 140, with Which may beengaged an end of an arm 141 on a rock-shaft 142, jonrnaled in suitablebearings.. Around therock-shaft is coiled a spring 143, (see Fig.3,)Avhich holds the arm 141 normally in inactive position, as shown inFig. 1 and by the dotted lines iii-Fig. 6. To the end of the shaft 142is affixed an arm 144, which forms the armature of an eleetromagnet145,` arranged vertically on the right-hand side of the maconnectedinseries With the motor and in multiple with the magnets 51 and 66.. Themovement of the armature away from the electromagnet is limited by astop-pin 146. When a current is passed through theelcctromagnet 145 thearmature 144 is attracted and the arm 141 is movedto the full-linepositionin Fig. 6, so as to arrest the paWl inoperative With relation tothe ratchetsegment 50. It will be recalled that each time any one of thekeys of the keyboard is manipulated by the operator the current Willeifects the feeding of the typeeivheel carriage and the operation of thetype-Wheel, and in order that the electromagnet 146 may be energized'tomove the feeding-pawl to inactive defressed it is arranged in ashunt-circuit 7L. 3. (See Fig. 17.) This circuit includes the bracket8.4, which is insulated fromthe remainder of the machine, the shaft 28for the type-Wheel, a portion of the frameworkl ofthe machine, Which inFig. 17 is indicated" Iat la', a ymovable switch 150, and a contactthemachine, but insulated therefrom. The

The contacts 152 and 153 Wil be engaged only when one ofthe shift-keys 'is manipucontact 153 in such position that vupon themovement of the type-Wheel to` printing position the contacts will notbe engaged.

From this description it Will be seen that the o erator to effect theshifting of the type- Wheel3 on its shaft in the manner described therock-shaft 142 Will be actuated by the' atmagnet 145 andthe arm 141 Willbe'moved .ing-sprin 58.

from the dotted position shown in Figi 6 .to 65 the full-line position,so as to preve t the ,feeding-pawl from dropping into afresh tooth ofthe carriage-ratchet segment 50.

Automatic switch m'ec7Lanism.-The switch 150, to which reference hasbeen made, is secur-led upon the shaft '93, which, as will beremembered, supports the'paper-feeding Wheel 86. By reference toFigs. 2,4,'and 17 it WillA be'seen that the switch 150,\Which is flexible andwhich When the shaft 93 is in its normal position rests u onthe contact151, normally completes an e ectrical connection from the type-Wheelshaft 28 to the electromagnet 145. In this embodiment of'thei'nventionit is necessary for the operator'when the type- Wheel carriage reachesthe Vend of a line to depress a shift-key in order that the carriage maybe automatically returned by the return-" To this end the electromagtvrnet 66, W 'ch when ener ized eH'ects the lift' ing of the retaining-paw?60, as hereinbefore described, is arranged inv a, branch circuit m inseries With the motor and in multiple withv the electromagneticmechanism Which effects the: feeding of the carriage and the actuationof vthe type-Wheel. B an examination of Fig. 17 it will be seen t at thebranch circuit m includes a contact-plate 160, arranged adjacent to butinsulated from the contactplate 151, so that itmay be engaged by thes'vvitch 150 when the shaft 93 is roc red by the spring 103 after therelease of the stop or stud 1-02 by the latch 106. v

Assuming that the carriage has reached the end of ajline and the sto 107has engaged the latch 106 and release the stud 102, the passa eCof adirect current of electricity through t eimagnet 51 causes the armature52 to rock the shaft 53 and lift the arm 108.

The arm 101 on the shaft 93 will then be rocked bythe spring 103 so asto bring the Switch against the stationary contact 160, so that currentWill flow through the branch circuit m when the contact 153 on thetvpe-wheel shaft engages thecontact 152 on the bracket 84, whichbracket, it will be re membered, is electrically connected with theswitch 150. -The magnet 66 bein thus ener- 'gized, the retaining-paWly60 Wil be lifted, carrying with it the feeding-pawl 55, so that thecarriage Will be automatically returned l by the spring 58 to itsstarting-point. It is freqliently desirable to feed the paper severalsteps-as, forinstance, to separate one paragraph of printed matter by alarge .space -from the preceding paragraph. Tins is accomplished Whenthe carriage has reached the end of its line, so as to free the latch106 from the stud 102 by the`manipulation of the space-l ey. When theparts are all in the position last,described, the operator maymanipulate the space-key as many times as he desires Without printingany character upon IOS .TIOl
